A fight in the street allegedly led to Stone being stabbed multiple times in the torso, prompting investigators to block off two blocks in the area, Sacramento police said.

Stone was taken to the hospital with non-life-threatening injuries, according to police.

A man and a woman were questioned by police, but there is no word that they were detained or taken into custody.

The area reopened about 6 a.m., but the investigation is ongoing.

No suspect description has been released.

Stone and two friends, Anthony Sadler and Alek Skarlatos, who all grew up in Sacramento, were hailed as heroes for stopping a terrorist attack on board a Paris-bound train.

Skarlatos returned last week to Roseburg, Oregon where he was living after a gunman opened fire on Skarlatos' college, Umpqua Community College, killing nine before before the shooter turned the gun on himself.
